Our photometry laboratory is equipped with state-of-the-art devices to evaluate luminance with remarkable precision.<br>Luminance is a measure of the perceived brightness of a surface or light source as seen by an observer. It is a physical parameter that characterizes the intensity of light emitted, reflected, or transmitted by a surface in a given direction. Luminance is often expressed in candela per square meter (cd\/m\u00b2) and is closely related to light intensity but also takes into account the apparent area of the source or surface.<br>In simpler terms, luminance is what our eyes perceive as the brightness of a surface or light source. It depends on both the amount of light emitted by the source or reflected by the surface and on how this light is distributed in our field of vision<\/p>\n\n\n\n<details class=\"wp-block-stackable-accordion stk-block-accordion stk-inner-blocks stk-block-content stk-block stk-dbad4fc is-style-plain\" data-block-id=\"dbad4fc\"><style>.stk-dbad4fc{border-style:solid !important;border-color:#dfdad1 !important;border-top-width:0px !important;border-right-width:0px !important;border-bottom-width:1px !important;border-left-width:0px !important;padding-bottom:24px !important}<\/style>\n<summary class=\"wp-block-stackable-column stk-block-column stk-column stk-block stk-59d855a stk--container-small stk-block-accordion__heading\" data-v=\"4\" data-block-id=\"59d855a\"><div class=\"stk-column-wrapper stk-block-column__content stk-container stk-59d855a-container stk--no-background stk--no-padding\"><div class=\"stk-block-content stk-inner-blocks stk-59d855a-inner-blocks\">\n<div class=\"wp-block-stackable-icon-label stk-block-icon-label stk-block stk-a92acd5\" data-block-id=\"a92acd5\"><div class=\"stk-row stk-inner-blocks stk-block-content\">\n<div class=\"wp-block-stackable-heading stk-block-heading stk-block-heading--v2 stk-block stk-ef608e8\" id=\"the-importance-of-luminance-measurements-in-r-amp-d\" data-block-id=\"ef608e8\"><h2 class=\"stk-block-heading__text\">The importance of luminance measurements in R&amp;D<\/h2><\/div>\n\n\n\n<div class=\"wp-block-stackable-icon stk-block-icon stk-block stk-f7bd861\" data-block-id=\"f7bd861\"><span class=\"stk--svg-wrapper\"><div class=\"stk--inner-svg\"><svg style=\"height:0;width:0\"><defs><linearGradient id=\"linear-gradient-f7bd861\" x1=\"0\" x2=\"100%\" y1=\"0\" y2=\"0\"><stop offset=\"0%\" style=\"stop-opacity:1;stop-color:var(--linear-gradient-f-7-bd-861-color-1)\"><\/stop><stop offset=\"100%\" style=\"stop-opacity:1;stop-color:var(--linear-gradient-f-7-bd-861-color-2)\"><\/stop><\/linearGradient><\/defs><\/svg><svg data-prefix=\"fas\" data-icon=\"chevron-down\" class=\"svg-inline--fa fa-chevron-down fa-w-14\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" viewBox=\"0 0 448 512\" aria-hidden=\"true\" width=\"32\" height=\"32\"><path fill=\"currentColor\" d=\"M207.029 381.476L12.686 187.132c-9.373-9.373-9.373-24.569 0-33.941l22.667-22.667c9.357-9.357 24.522-9.375 33.901-.04L224 284.505l154.745-154.021c9.379-9.335 24.544-9.317 33.901.04l22.667 22.667c9.373 9.373 9.373 24.569 0 33.941L240.971 381.476c-9.373 9.372-24.569 9.372-33.942 0z\"><\/path><\/svg><\/div><\/span><\/div>\n<\/div><\/div>\n<\/div><\/div><\/summary>\n\n\n\n<div class=\"wp-block-stackable-column stk-block-column stk-column stk-block stk-14d6a70 stk-block-accordion__content\" data-v=\"4\" data-block-id=\"14d6a70\"><style>.stk-14d6a70-container{padding-top:0px !important;padding-right:0px !important;padding-bottom:0px !important;padding-left:0px !important}<\/style><div class=\"stk-column-wrapper stk-block-column__content stk-container stk-14d6a70-container stk--no-background stk--no-padding\"><div class=\"stk-block-content stk-inner-blocks stk-14d6a70-inner-blocks\">\n<p class=\"wp-block-paragraph\">In the field of research and development, luminance measurements are proving to be of crucial importance in ensuring product quality and performance.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">At PIS\u00c9O, we understand the importance of having accurate and reliable data to make informed decisions throughout the development process.
